Be it known that I, ADOLPH K. BRAUER, a citizen or' the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Sprinkling Nozzle, of which the of the sprinkler shown in Fig. 4.

following is a specification.

This invention relates to nozzles adapted Vfor sprinkling lawns, for irrigating gardens, fields and other tracts ot' land, and for sprinkling systems installed for lire protection in stores, warehouses and other -buildings. y

An object of this invention is to provide cheap, convenient and easily-installed nozzles whereby lawns and other grounds may be irrigated by surface sprinkling, and also to provide a cheaper construct-ion for tire extinguishing sprinkler systems.

An object of this invention is to provide a nozzle adapted for use in a sprinkling system whereby all the nozzles-will receive the same water pressure and thereby produce an even sprinkling of water on all portions covered by the sprinkling system.

Another object of this invention is to provide a sprinkling nozzle which will'havc an even spray of water emitted therefrom at every point on the periphery of the ori lice.

The new construction of sprinkler nozzle may be made in different forms and it will only be necessary to illustrate the invention by showing one or two of such forms, it being understood that the nozzle may be made with or without a spike and with or without a stabilizing lug.

Other objects and advantages may appear .from the accompanying drawings, the subjoined detail description and the appended claim.

The accompanying drawings illustrate the invention.

Figure l is a aers ective view of an irrigating sprinkler syst/em for use in a lawn,

iield or garden, and being equipped with sprinkling nozzles embodying this invention.

Fig. 2 is a perspective viewof a fire extinguishing sprinkler system equipped with nozzles constructed in accordance with features of this invention.

Fig. 3 is a tragmental plan of a stationary irrigating sprinkler system equipped with nozzles constructed in accordance with features of this invention.

111g. 4 isa plan, partly in section, of a sprinkler of the centrifugal type, constructed 4 Vin'accerdance with this invention.

Fig. 5 is an elevation of the intake side The sprinkler comprises a body 1 having a practically circular chamiber 2, a tangential duct 3 opening thereinto and a centrally arran red sprinkler oriice 4.'

T e sprinkler body is dat and the intake and outlet arer coaXially arranged at one edge of such body at the same side of the body with the tangential duct 3. vThis con-`r struction is considered preferable forboth the irrigating system and the fire extinguishing system 'because the dat form and radial distribution adapt themselves most readily to the conditions involved.

On one side of the body l, and tangential to the outer periphery ofthe circular chamber 2, there is provided a straight-nipple constituting a supply chamber 5 having a threaded intake 6 at the end opposite the tangential duct or. passageway 3, and a threaded outlet 7 at the end adjacent to said tangential duct.l rl`he duct or passageway 3 which leads from the supply chamber 5 to the circular vortical chamber 2 is tangential to the outer periphery of said vortical chamber 2, and narrows inwardly toward said vertical chamber which vortical chamber has ay concave top and an orifice et. The intake 6 is adaptedy for connection with a coupling 8 of a flexible pipe or hose 9 in Fig. l, or with a piece of rigid metal pipe as at 10 in Figs. 2 or` 3, and the outlet 7 leading from the sprinkleris adapted for like connections. Each connecting pipe 9 is connected. at one end with the outlet of one sprinkler and at the other end ,with the intake of a succeeding sprinkler.

In practice with the form ot sprinkler system shown in Fig. l, the sprinklers may or may not be provided with spikes and lugs 14, 14:', or with either. Sections 9 of hose of appropriate length will be respectively screwed int'o intake 6 of one sprinkler and outlet 7 of another.

To construct the system shown in Fig. l, a section of hose a, adapted to be attac-hed to the garden valve or hose-bib b at the hydrant c will bev'connected to the ,intake Jof thefrst sprinkler. .A hose section 9 corresponding to the section a Will be screwed into the outlets 7 ofsaid sprinkler at one end and into an intake 6 of `a second sprinkler at the other end. Other sections 9. of hose are in like manner attached to other sprinklers inthe Same manner until at the last sprinkler a plug Will be inserted into the outlet to close the system.

When it is desired to install and use the connected irrigating sprinkler-'system shown in F1g.v1, the hose section a is attached to all of the ground may be properly sprinkled.

rThe arrangement shown in Fig. 2` is of substantialply the same character as that shown in that the sprinklers are inverted and sections of metall' pipe 1b connect the sprinklers 17, and the systemis held in place onthe ceiling by suitalble loops 18 fastened to the ceilin 19.

- any usual thermostatic deviceJ not shown, or

by a valve 20.

In the. form shown in Fig. 8, the rigid pieces of pipe 21 correspond in function tol the pipe connections formed by the hose sections 9, except that said hose sections are flexible and are applied toI use on the surn face of theground while the pipe sections 21 are rigid and may be buried in the ground.

By arranging the threaded intake 6 and ig. 1; the only difference beingl ater may be automatically turnedon by outlet 7 coaxially as shown, 'the sprinkler is especially adapted for use as a part of the connected vsprinkler system, andtV by arranging the vertical chamber tangentially to the straight nipple thereby leaving said nipple free from obstructions each nozzle will receive the same amo-unt of pressure from the Water of the water' line and thereby an equal sprinkling will be obtained from all the nozzles of the sprinkler system, and the water line of which may thus be extended to cover an area of any length. The area covered by sprinklers controlled by one valve maiythus be indefinitely extended.

. y having the passageway 3 odset or tangential to the outer periphery of the vortical chamber a true circular and vortical action of the wate-r is set up in the vortical chamber and thus produces an even spray of Water at all sides of the opening.

I claim:

In a sprinkling nozzle, a nipple having an alined inlet and outlet; a Hat circular vortical chamber formed outside of said nipple and tangential thereto and having a concave upper face provided with a central opening; and a curved passageway leading from the interior of said nipple into the vortical chamlber, said passageway narrowing inwardly toward said vortical chamber and the orifice thereof and being formed opposite to the inlet and adjacent to the outlet of said nipple and tangential to the outer periphery of said chamber.

ln testimony whereof, I have hereunto set my hand at Los Angeles, California, this 24th day of April, 1917.

ADOLPH K. BRAUER.
